CP2105, CP2108 and CP2102N have vendor requests that can be used to
retrieve the firmware version. Having this information available is
essential when trying to work around buggy firmware as a recent CP2102N
regression showed.
Determine and log the firmware version also for CP2105 and CP2108
during type detection at probe.
